There are other ways to specify an empty string e.g $$$$. I don't
think we want to list all of them here.
We don’t, but we get the intended benefit by listing the by far most likely way anyone would actually write an empty string here. The comment within string_literal covers any edge cases sufficiently. The ‘’ can behave as a label of sorts just like “string_literal”.
I haven’t looked for similar precedent for this idea though and don’t feel strongly that we need to introduce it here, just something to consider to make the most read portion of any reference chapter imply this behavior.
